MySQL export table to text file fields name - mysql

Question

let's say I have the following table in MySQL
create table test_tbl
(
col1 varchar(100),
col2 varchar(100),
amount int,
created datetime
)
Data insert
Insert into test_tbl values('unu', 'doi', 10, '05/01/2015');
Insert into test_tbl values('patru', trei', 400, '04/01/2015');
I need export all the data from that table in the following format. The file should be txt file.
"col1"="unu","col2"="doi","amount"="10","created"="05/01/2015"
"col1"="patru","col2"="trei","amount"="400","created"="04/01/2015"
So the logic is:
Each column name with value separated by comma.
Does it possible get such result in MySQL ?

Answer 1

For export the table's data-
SELECT CONCAT('"col1"="',col1,'","col2"="',col2,'","amount"="',amount,'","created"="',DATE_FORMAT(created,'%d/%m/%Y'),'"') t FROM test_tbl INTO OUTFILE '/tmp/test.txt' CHARACTER SET latin1 FIELDS ENCLOSED BY '' LINES TERMINATED BY '\r\n';
For import the table from csv
mysql> CREATE TABLE `test_tbl` (
-> `col1` varchar(100) DEFAULT NULL,
-> `col2` varchar(100) DEFAULT NULL,
-> `amount` int DEFAULT NULL,
-> `created` datetime DEFAULT NULL
-> ) ENGINE=InnoDB DEFAULT CHARSET=latin1
-> ;
Query OK, 0 rows affected (0.44 sec)
mysql> load data local infile 'test.txt' into table test_tbl fields terminated by ',' ENCLOSED BY '"' lines terminated by '\r\n' (#col1, #col2,#col3,#col4)
-> set col1 = substr(#col1,8), col2 = substr(#col2,8), amount = substr(#col3,10), created = str_to_date(substr(#col4,11), '%d/%m/%Y');
Query OK, 2 rows affected (0.09 sec)

mysql> select * from test_tbl;
+-------+------+--------+---------------------+
| col1 | col2 | amount | created |
+-------+------+--------+---------------------+
| unu | doi | 10 | 2015-01-05 00:00:00 |
| patru | trei | 400 | 2015-01-04 00:00:00 |
+-------+------+--------+---------------------+
2 rows in set (0.00 sec)

Answer 2

Maybe this could work.
Use CONCAT to build a string like this
SELECT
CONCAT('"col1"="',col1,'","col2"="',col2,'","amount"="',amount,'","created"="',created,'"') t
FROM test_tbl;
Then you can also dump it to a text file using INTO OUTFILE.
SELECT
CONCAT('"col1"="',col1,'","col2"="',col2,'","amount"="',amount,'","created"="',created,'"') t
FROM test_tbl
INTO OUTFILE 'C:/yourtextfile.txt'
CHARACTER SET latin1
FIELDS ENCLOSED BY ''
LINES TERMINATED BY '\r\n';
Since CONCAT only has 1 row, you dont need to enclose any columns/fields with value since they are customised. Only a line break is used to terminate each ROW.
Hope it works!
